FIELD OF THE INVENTION

[0002] The present invention relates to telecommunications systems and,in particular, to an improved system and method for multimediatelecommunications system management.

BACKGROUND OF THE INVENTION

[0003] Many modern homes today have a television, a videotape recorder,a cable or satellite connection, and a personal computer with anInternet connection. Because these devices are relatively expensive andoffer complementary features, there have been efforts to converge thetelevision technologies with the personal computer/Internettechnologies.

[0004] For example, some personal computers have been equipped withtelevision tuner cards, which allow the reception of televisionprogramming through the cable or satellite connection. Such televisiontuner cards can also be equipped with video capture capabilities, toallow later playback of captured programming. However, equipping apersonal computer with video capabilities has not gained wide acceptanceamongst the general public as a replacement for a television, in partbecause the typical personal computer monitor is relatively small and,in particular, significantly smaller than the typical family roomtelevision. Moreover, the typical personal computer is equipped with arelatively more limited and inferior sound system, which can bedisadvantageous when marketing to modern viewers who require, forexample, high-fidelity sound or even a Surround Sound system. Anotherconvergence approach, known as WebTV, has been to provide the televisionwith a set-top box and keyboard to allow, for example, Internet accessthrough the television set and cable connection. While such systems areadequate for simple e-mail communication and limited Web browsing, WebTValso has failed to gain widespread acceptance, at least in part becausethe resolution of the typical television is much more crude than that ofthe computer monitor, and can also produce formatting idiosyncrasieswhich can make it difficult to view many web pages.

[0005] Each of these systems suffers from additional disadvantages whichmay have contributed to the failure to develop an effective convergedvideo system: Personal computers are frequently upgraded and replaced;television sets and home entertainment systems, however, have asignificantly longer life span.

[0006] As such, there is a need for a multimedia telecommunicationssystem that provides improved convergence of television and personalcomputer based resources. There is a further need for a convergencesystem that allows the user to maintain separate television and personalcomputer based resources.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0059] System Overview

[0060] Turning now to the drawings and, with particular attention toFIG. 1A, a multimedia telecommunications system according to anembodiment of the present invention is shown and generally identified bythe reference numeral 100 a. As will be discussed in greater detailbelow, the multimedia telecommunications system 100 a provides userswith a bridge between their personal computer and their homeentertainment system. The multimedia telecommunications system 100 areceives broadband media (e.g., audio and video) streams from abroadband signal source, and digitizes, encapsulates and transmits toand from a personal computer using a local area network technology, suchas a wireless LAN, for intelligent processing, recording and controlfrom the personal computer. Digital video can also be captured from theInternet and sent for playback on the home entertainment system.

[0061] In particular, shown is a multimedia telecommunications system100 a including a media stream manager, referred to as a digitalpersonal video stream manager 102 a (DPVSM), according to an embodimentof the present invention. The system 100 a includes a media or homeentertainment subsystem 101 a and a network or computer subsystem 103 a.As will be described in greater detail below, the media subsystem 101 ais based around a television 116 a and other broadband media devices,while the network subsystem 103 a is based around a personal computer110 a and other local area network devices.

[0062] As shown, the DPVSM 102 a is coupled via a cable set-top box 112a to a house cable connection 104 a. The cable set-top box 112 a may beany standard cable box or broadband media interface such as, forexample, a satellite dish interface. The house cable connection 104 atypically may be a connection for a coaxial cable, but other connectionsare contemplated. As shown, the DPVSM 102 a further may couple to anaudio system 118 a, and, via a video recorder 114 a to a television 116a. The video recorder 114 a may be embodied, for example, as any of avariety of video recording devices, including, for example, avideocassette recorder (VCR) or an optical disk recorder. In addition,an infrared (IR) remote control 120 may be provided for control of theDPVSM 102 a and various of the other components of the system. The IRremote 120 may be any remote capable of interacting with atelevision-screen based interface and allowing the user to makeselections herefrom.

[0063] The DPVSM 102 a may be adapted to control various functions ofthe various components of the media subsystem 101 a, such as turning onand off the various devices, or programming the video recorder forfuture program recording. The DPVSM 102 a may program the devices viatheir coaxial cable connections, in much the same way a cable companycontrols operation of the cable set-top box. In other embodiments,separate control interfaces, such as wireless interfaces or infraredinterfaces, may be provided. For example, if the video recording devicehas an infrared interface, the DPVSM 102 a could similarly send infraredcontrol signals to the video recording device for control thereof.

[0064] As will be described in greater detail below, the DPVSM 102 a cancommunicate with elements of the network subsystem 103 a wirelessly overa local area network 107 via an 802.11 antenna 105 a. In particular, inthe embodiment illustrated, the network subsystem 103 a couples to thehouse cable connection 104 a via an Internet access device such as acable or DSL modem 106 a. It is noted that, in embodiments in which themodem is a DSL modem, an Internet connection separate from the cableconnection would be provided. The modem 106 a couples to a home 802.11router 108 a and a personal computer 110 a, which may be a laptop ordesktop computer. In the embodiment illustrated, the router 108 acouples to the modem 106 a and the PC 110 a via CAT5 cable. It is noted,however, that other interfaces, such as wireless interfaces, could beused instead of CAT5 cable. The PC 110 a is equipped with an Ethernetnetwork interface card (NIC) 107 a, or other network interface, forcommunicating with the router 108 a. As will be described in greaterdetail below, the PC 110 a is able to communicate, for example, controlcommands 4555, with the DPVSM 102 a via the wireless router 108 a, tocontrol various elements of the media subsystem 101 a. It is noted thatan advantage of certain embodiments of the DPVSM 102 is that it need notprovide its own mass storage device for storing media files; rather, itcan make use of the personal computer 110 a's storage.

[0065] More particularly, turning now to FIG. 2A, a block diagram of theexemplary DPVSM 102 a of FIG. 1A is shown. In the embodimentillustrated, the DPVSM 102 a includes a control processor 202 and anaudiovisual or multimedia interface 204. The multimedia interface 204receives audio and/or video over the cable connection 104 a (FIG. 1A) orother audio/video input to a multimedia interface such as an audio/videoanalog-to-digital converter 206. The video signal is then received at acompression circuit 208 for conversion into, for example, MPEG format.The MPEG video is then provided to an Ethernet interface 210 for packinginto Ethernet packets. The Ethernet packets are then provided to a localarea network interface, such as a wireless 802.11 interface 212 fortransmission to the 802.11 router, if desired. The video can then betransmitted to the personal computer 110 (FIG. 1A). Thus, the DPVSM 102a provides an interface for receiving video signals from the cable orsatellite TV connection, and converting them into a digital formatreadable by the personal computer 110.

[0066] Similarly, Internet audio and video content can be received bythe 802.11 router 212 from the personal computer 110 a and displayedover the television or recorded on the video recording device 114 a.Thus, the data is unpacked from the Ethernet packets at 214. If in, forexample, MPEG format, the resulting data is decompressed in thedecompression unit 216 and provided to the video recording device 114 aor television 116 a via the audio/video digital-to-analog converter 218.It is noted that, in certain embodiments, the audio-video signalarriving over the cable connection and cable box may already be indigital format. Thus, the analog-to-digital and digital-to-analogconverters 206, 218 may not be necessary, although conversion betweendigital formats may be required.

[0067] The control processor 202, which may be embodied as aPentium-type or other microprocessor or microcontroller, provides asupervisory function for the other components of the media subsystem 101a and can receive and store commands in memory 203 for later execution,such as recording a program using the video recording device 114 a, aswill be explained in greater detail below. The control processor 202 isthus coupled to send and receive control signals via the wireless 802.11interface 212. The control processor 202 may also be coupled to orimplement other control interfaces, such as an infrared module interface222, a Universal Serial Bus (USB) interface 220, and a television userinterface 224.

[0068] The USB interface 220 allows peripheral devices to be coupled inand played back; for example, a camera could be coupled to the USBinterface 220. The television user interface 224 is used to generate auser interface for display on the television screen, in much the sameway that a videocassette recorder or digital versatile disk (DVD) playerprovides a control interface. The IR module 222 allows reception ofcommands and selections using an IR remote control 120 in conjunctionwith the television user interface 220.

[0069] As noted above, a multimedia telecommunications system accordingto embodiments of the present invention includes a media subsystem 101 aand a network subsystem 103 a. The network subsystem 103 a is basedaround a personal computer 110 a, such as the personal computer shown inFIG. 3, which can access the Internet via the cable or other connection.As shown, the personal computer 110 a includes one or more processors302 implementing one or more software modules. In the exampleillustrated, shown are a user interface module 304, a DPVSM controllermodule 312, and a video editor module 310. One or more of these modulesmay be embodied as Web browser plug ins. As will be described in greaterdetail below, the user interface module 304 allows video to be displayedon the computer monitor (not shown) and for various files and controlsto be executed. The DPVSM controller module 312 permits viewing orplayback of locally stored media files, such as audio or video files,and control of the DPVSM 102A (FIG. 1A). The video editor 310 allowsediting of local video files and may be implemented as any of a varietyof video editing programs. As will be discussed in greater detail below,the media files may be media files downloaded from the Internet or maybe captured from the media subsystem 101.

[0070] The processor 302 may couple to a wireless LAN interface 306(e.g., a 802.11 Ethernet NIC) to receive audio and video streams fromthe house cable connection 104 a and the media subsystem 101 a (FIG.1A). In addition, the processor 302 couples to a memory 304 for storingmedia files 305 and programs (not shown). The personal computer 110 aalso may include an infrared interface 306 for using an infrared mouseor keyboard control. Finally, in certain embodiments, a service providermay maintain a web site that allows use of the personal computer 110 todownload upgrades to the DPVSM 102's control programs and modules.

[0071] As noted above, a multimedia telecommunications system accordingto embodiments of the present invention may take a variety ofconfigurations. One such configuration is shown in FIG. 1A; another isshown in FIG. 1B. In particular, FIG. 1B illustrates a personal digitalvideo system 100 b including an integrated digital personal video streammanager 102 b. In this embodiment, the digital personal video streammanager 102 b includes an integrated Internet access device such as acable or DSL modem and an integrated 802.11 router, as will be explainedin greater detail below.

[0072] As shown, the system 100 b of FIG. 1B includes a house cableconnection 104 b connecting to the cable provider. A cable set-top box112 b couples the house cable connection 104 to the integrated digitalpersonal video stream manager 102 b. The digital personal video streammanager 102 b then couples to an audio system 118 b, a video recordingdevice 114 b, and television 116 b. It is noted that in otherembodiments, the cable set-top box 112 b may also be integrated with thedigital personal video stream manager 102 b.

[0073] A personal computer 110 b, which can be either a desktop or alaptop computer, is also supported and can include an 802.11 networkinterface card or PC Card 107 b. Thus, the personal computer 110 bitself need not support a modem or other Internet connection, beyond theNIC. The personal computer 110 may be provided with a firewall, such asfirewall 308 of FIG. 3, however.

[0074] As can be appreciated, the digital personal video stream manager102 b with an integrated cable modem is convenient when the serviceprovider is also the cable company. If the Internet connection is a DSLconnection or other telephone connection, then a separate DSL modem andtelephone jack also could be integrated with the DPVSM 102 b.

[0075] A block diagram of an exemplary integrated digital personal videostream manager 102 b is shown in FIG. 2B. As shown, the digital personalvideo stream manager 102 b includes a control processor 202 b and anaudio/video interface 204 b. The audio/video interface 204 b isgenerally similar to that of FIG. 2A, and includes an wireless LANaccess point (e.g., Ethernet and wireless 802.11 interface 210 b, 212b). An integrated cable or DSL modem 106 b is also provided, as is anintegrated 802.11 router. Other components are generally similar tothose of FIG. 2A and can include a memory 203 b, an Infrared controlinterface 222 b, and a Universal Serial Bus interface 230 b.

[0076] In what follows, for sake of clarity, in describing operation ofembodiments of the present invention, the system of FIG. 1A and FIG. 2Awill be referred to, it being understood that the teaching of thepresent invention are applicable to a variety of network and deviceconfigurations.

[0077] According to one aspect of the present invention, video that isseen on the personal computer 110 a may also be viewable via the DPVSM102 a on the television 116 a, and vice versa. This is illustratedschematically with reference to FIG. 4. In particular, shown are acomputer monitor 402 and a television screen 404. Also shown are thedigital personal video stream manager 102 a and a video recording device114 a. Other elements of FIG. 1A are omitted for clarity.

[0078] As shown, a video 403 a, representative of a video file, forexample, is viewable on the monitor 402. The video 403 a may be anInternet media file downloadable from the Internet 406, via the housecable or other Internet connection 104 a. According to embodiments ofthe present invention, the video 403 a can be transmitted to the digitalpersonal video stream manager 102 for conversion into a television videoformat and viewable on the television screen 404, as video 403 b. Thevideo 403 a can further be recorded onto a recording medium such asvideotape using the video recording device 114 a. Similarly, a video 403b being shown on the television screen 404, either from the cableconnection or on replay from the recording device 114 a, can betransmitted via the digital personal video stream manager 102 fordisplay on the personal computer 110 a as a video file 403 a.

[0079] The digital personal video stream manager 102 a can be controlledfrom either the personal computer 110 a or using an infrared remotecontrol 120 a, via a graphical interface using the television screen.FIG. 5A and FIG. 5B illustrate exemplary user interfaces for suchpurposes.

[0080]FIG. 5A illustrates an exemplary user interface viewable on thecomputer monitor and generated, for example, by a digital personal videostream manager program which may be implemented as a Web browser plugin. Shown are three windows: a web scheduler 502; a DPVSM control window504; and a File Manager window 506.

[0081] The DPVSM program window 504 allows activation of the DPVSM,selection of files, recording, scheduling, and the like. It can also beused to activate or interface with the web scheduler 502 and the filemanager 506.

[0082] The web scheduler 502 may be a web page accessible via theInternet set up by the service provider, or it may be an individualnetwork's web page. In certain embodiments of the present invention, theuser can access the web page to determine a network program schedule andcontrol the digital personal video stream manager 102 a and thus thevideo recording device 114 a to record a program remotely. For example,the user could click on a selected program 508, including the time anddate and channel. This information can then be downloaded to the DPVSMcontrol program 312 (FIG. 3) and either stored at the computer ortransmitted to the digital personal video stream manager 102 a itself.At the designated time, the digital personal video stream manager 102 acauses the video recording device 114 a to record the selected program.Alternatively, the DPVSM control program 312 can be used to record theprogram as a video file 305, stored on the computer 110 a.

[0083] The file manager 506 can be used to access stored media files andselected for playback either as files on the computer or converted andtransmitted to the digital personal video stream manager 102 a forviewing on the television.

[0084] Similarly, FIG. 5B illustrates exemplary user interfaces that canbe generated by the digital personal video stream manager 120 a anddisplayed on the television. The user can scroll through and makechoices using, for example, an infrared remote 120 (FIG. 1A) in much thesame way that a typical video cassette recorder can be programmed. Thus,the television interface of FIG. 5B includes an entry screen 550 formaking a mode selection (e.g., TV, VCR, DPVSM). Selection of the DPVSMmode may cause display of a screen such as screen 552. The screen 552allows for file select, record, set channels, time, and VCR or digitalfile format, among other things.

[0085] Turning now to FIG. 6, a signaling diagram illustrating operationof various aspects of the present invention is shown. In particular,signaling for television or broadband recording, either on video or asdigital files is shown. Shown are the cable connection 104, DSL or cablemodem 106, 802.11 router 108, personal computer 110, cable box 112,digital personal video stream manager 102, video recording device 114,television 116, and IR remote 120.

[0086] Recording using the video recorder 114 by use of the personalcomputer 110 or the infrared remote 120 is shown at 601. Personalcomputer-controlled remote recording is initiated at 602 a, where thepersonal computer 110 can send one or more record commands via the802.11 router 108 to arrive at the digital personal video stream manager102 at 604 a. The digital personal video stream manager 102 then sends acorresponding command to the video recorder 114 to set the time and dateand channel of the recording. Alternatively, the user can employ the IRremote 120 to control or program recording via the digital personalvideo stream manager 102. Thus, at 602 b, the user can send one or morecontrol signals to the digital personal video stream manager 102, whichcauses a display on the television 116 of the user interface, such asthat of FIG. 5. The user can then program the video recorder 114 at 604b. In either case, the broadband video signal is received from the cableconnection 104 and recorded at the video recorder 114 at 606.

[0087] The personal computer 110 can also be used to control recordingof the broadband signal as digital video files, as shown at 603. At 608,the personal computer 110 sends a command 608 via the 802.11 router 108to the digital personal video stream manager 102, as shown at 610. At612, the broadband video signal is received from the cable connection104 to the digital personal video stream manager 102 via the cable box112. The digital personal video stream manager 102 then converts thereceived broadband signal to a digital file format and transmits it viathe 802.11 router 108, as seen at 614, 616, to the personal computer110. The personal computer 110 can then store the file in its mediadatabase for alter playback.

[0088] The IR remote 120 can also be used to control recording ofbroadband video as digital files, as shown at 605. At 618, the IR remote120 is used to contact and send commands to the digital personal videostream manager 102. At 620 b the DPVSM 102 activates the TV based GUI,which is then used to program or control the recording of the selectedprogram. At 620 a, the DPVSM 102 sends the commands via the router 108to the personal computer 110 at 622. At 624, the broadband signal isreceived from the cable connection 104 to the DPVSM 102. The DPVSM 102then converts the received broadband signal to one or more digital filesand transmits them to the personal computer via the 802.11 router, at626, 628.

[0089]FIG. 7 is a signaling diagram illustrating video playbackaccording to an embodiment of the present invention. Shown are the cableconnection 104, DSL or cable modem 106, 802.11 router 108, PC 110, cablebox 112, DPVSM 102, VCR 114, TV 116, and IR remote 120.

[0090] Personal computer control of playback of digital files is shownat 701. At 702, the personal computer 110 can be used to access thedatabase in memory and play one or more selected files. The selectedvideo file can also be played on the television via the DPVSM 102. Thus,the personal computer 110 can be used to select a file and designate itfor playback on the television 116. At 706, the personal computer 110sends a command via the router 108, which is received at the DPVSM 102,at 708. The DPVSM 102 then converts the received file into a formatuseable by the video recorder 114 and transmits it via the video cableto the video recorder, at 710. If the video recorder 114 has a tape, thefile can be recorded by the tape and played on the television 116, at712.

[0091] The use of the personal computer 110 to control tape playback isshown at 703. The personal computer 110 can activate its DPVSM controlprogram 312 (FIG. 3) and select a tape control option(s). At 714, a tapeplay command is transmitted to the router 108, which then provides it tothe DPVSM 102 at 716. At 718, the DPVSM 102 reads the command anddirects the video recorder 114 to play the tape. If desired or ifselected originally, the tape can play on the television 116, as shownat 719. If it is wished to play the tape on the personal computer 110,then at 720, the DPVSM 102 receives the tape broadband signal andconverts it into a video digital file format and transmits it to therouter 108 at 721. At 722, the router 108 then provides the file to thepersonal computer 110 for display using the video software.

[0092] As noted above, the IR remote 120 can also be used to playbackdigital files, either via the television 116 or on the personal computer110, as shown at 705. At 724, the IR remote 120 is used to send one ormore control signals to the DPVSM 102. At 726, the DPVSM 102 displaysthe GUI on the television screen. At 728, the user can use the IR remote120 to select a file for viewing, and whether it is to be viewed on thetelevision 116 or the personal computer 110. The selection istransmitted to the personal computer 110 via the router at 730 and 732.The personal computer 110 then selects the file from the database 305(FIG. 3) and transmits it to the DPVSM 102 via the router 108, at 734,736. Alternatively, the personal computer 110 can simply run the filelocally on the PC monitor. If selected for TV display, the DPVSM 102then converts the file for display by the television 116. As discussedabove, this may be done concurrently with recording the video stream ona tape inserted into the video recorder 114.

[0093] The IR remote 120 can also control playback of a tape inserted inthe video recorder 114, either at the television 116 or the personalcomputer 110. As seen at 738, a tape in the video recorder 114 can beplayed back on the television 116. The IR remote 120 can then send asignal to the DPVSM 102, at 740. At 742, the DPVSM 102 displays thetelevision based GUI. At 744, the IR remote 120 can be used to select a“Play Tape on PC” option. The DPVSM 102 then receives the video signalfrom the video recorder 114 and converts it to the digital file format.It is then transmitted to the personal computer 110 via the router 108for playback, at 746, 748.

[0094] As noted above, one aspect of the present invention is an abilityto schedule recording of television programming using a World Wide Webinterface. This is illustrated more particularly with reference to FIG.8. Shown are the cable connection 104, DSL or cable modem 106, 802.11router 108, personal computer 110, cable box 112, DPVSM 102, videorecorder 114, television 116, and IR remote 120. At 802, the personalcomputer 110 logs in to a service provider 122 using an Internetconnection via the DSL or cable modem 106. The service provider 122 maymaintain a web site having television schedule information in asubscriber-accessible format, which is then downloaded to the user'sbrowser, at 804. The personal computer 110 can then display the scheduleor schedules as described above and select one or more programs forrecording. Then, at 806 and 808, the personal computer 110 can send acommand to the DPVSM 102 via the router 108 that it should supervise therecording of the selected programming. The DPVSM 102 then stores theinformation until the designated time and then activates the videorecorder 114 and cable box, if necessary. The video recorder 114 willthen receive the programming at 814, which can then be recorded on thevideo recorder 114. In addition, or in the alternative, the receivedbroadband signal can also be converted by the DPVSM 102 into the digitalfile format and transmitted to the personal computer 110 for storage, at816, 818.

[0095] Integrated Audio Stream Manager

[0096] According to one aspect of the present invention, an audio streammanager is provided in a manner similar to that of the video streammanager discussed above. More particularly, such an audio stream managerprovides a digital jukebox which allows audio streams to be recordedfrom media disks, such as compact disks (CDs), or downloaded from theInternet and then played through the DPVSM 102 and stored on thepersonal computer 110. The audio streams are accessible by a file systemor master index generated from downloaded CD databases of playlists.

[0097] The audio stream manager may be embodied, for example, as asystem similar to the systems of FIG. 1A and FIG. 1B. For clarity ofdiscussion, FIG. 9 is a diagram schematically illustrating an integratedaudio stream manager according to an embodiment of the presentinvention. Shown are a DPVSM 102, an audio system 118, a personalcomputer 110, and one or more CD database servers 904, typicallyaccessible via the Internet.

[0098] The personal computer 110 includes a jukebox utility 900 and alocal media disk player 901 such as a compact disk or DVD player. Thepersonal computer 110's memory 304 may be used to store music or otheraudio files 909. As will be discussed in greater detail below, thejukebox utility 900 is capable of converting a received CD track into adigital file format, such as MP3; downloading song lists from Web sites;and creating DPVSM-readable lists of songs or audio files for use inaccessing the corresponding audio files 909 for playback. The audiofiles 909 are then available through a graphical user interface, eitheron the television 116 (FIG. 1A) or on the personal computer 110.

[0099] The DPVSM 102 may include an audio interface for coupling to theaudio system 118 and the personal computer 110 via the network; such aninterface is generally similar to the interface 204 (FIG. 2A) for usewith video. The DPVSM 102 may also include a jukebox control utility902, typically implemented by the controller 202, for communicating withthe jukebox utility 900 and generating a jukebox user interfaceaccessible via the television screen, in a manner similar to thatdiscussed above with reference to the video streams.

[0100] Exemplary use of an Internet CD playlist database as a basis forDPVSM indices is shown in FIG. 10. Shown in FIG. 10 are a Web page 903having an exemplary CD database entry 904. As shown, the CD databaseentry 904 includes at least a CD identifier 1020 and a list of tracks1022. The user can use his personal computer 110's web browser tomanually or automatically access the web page 903 and download the CDdirectory and associate each track with a file name. This is illustratedmore particularly at 1002, which shows an exemplary CD or jukebox filelisting 1002, typically stored in memory 305. Shown at 1002 are the CDname 1004, track identifiers 1005, and filenames 1006 associatedtherewith. It is noted that these filenames 1006 may be default filenames based on the track identifier or may be user input.

[0101] Once the particular CD has been entered and its tracks convertedto digital file format, the CD is indexed in a master list, such as thatshown at 1008. In particular, shown at 1008 are a filename listing 1009a, a CD listing 1009 b, and a track listing 1009 c for each file 1010 a,1010 b . . . 1010 n. The listings can be arranged by CD, oralphabetically by file name, or randomly, any other desired ordering forplayback or selection.

[0102] Operation of the audio stream manager according to an embodimentof the present invention is shown in the flowchart of FIG. 11. In step1102, a user of the personal computer 110 can insert a disk into theplayer 901 (FIG. 9). At step 1104, the jukebox utility 900 converts thereceived CD track into a digital file format, such as MP3, and stores itin memory 305 as an audio file 909. At step 1106, the jukebox utility900 accesses a predetermined Internet Web site 903 having a database ofCDs and track listings, corresponding to the converted CD. The listingis then downloaded by the jukebox utility 900 and formatted into anindex 1008, in step 1108. It is noted that, in other embodiments, theuser could simply type in an index of his own making. At step 1110, thejukebox utility 900 sends the index to the DPVSM 102 and, particularly,to the control utility 902. At step 1112, the DPVSM 102 can be used todisplay the index listing on the television screen. At step 1114, theuser can use a remote, such as an infrared remote 120, to select thedesired track or audio file. Finally, at step 1116, the DPVSM 102 willreceive the file via the network and play the selected file on the audiosystem 118. It is noted that in certain embodiments, the DPVSM 102 canconvert an audio file from a digital format to an analog format, orbetween digital formats, or merely act as a “conduit” to relay a digitalfile for playback on the audio system. Thus, the audio system may beembodied as any of a variety of known analog or digital audio systemscapable of playing, for example, compact disks or MP3 files or receiveradio transmissions.

[0103] Operation of an embodiment of the present invention is shown ingreater detail with reference to the signaling diagram of FIG. 12. Shownare the cable connection 104, DSL or cable modem 106, 802.11 router 108,personal computer 110, cable box 112, DPVSM 102, video recorder 114,television 116, and IR remote 120.

[0104] At 1202, the user can insert a compact disk into the CD or DVDplayer 900 of the personal computer 110. At 1204, the jukebox utility900 on the personal computer 110 converts the file to a digital fileformat, such as an MP3 format. At 1206, the jukebox utility 900 uses thePC's web browser to access the Internet web site having the CD databaseand downloads it to the personal computer 110, at 1208. It is noted thatthe jukebox utility 900 may be implemented as one or more Web browserplug ins.

[0105] At 1210, the jukebox utility 900 creates an index or includes thecurrent CD listing in an existing index. At 1216, the user can select atrack or filename for playback. The selected file is then sent to theDPVSM 102 for playback via the router 108, at 1212 and 1214. The DPVSM102 then plays the file on the audio system 118. Alternatively, theindex could be sent to the DPVSM 102, which then generates a televisionbased GUI, which can be selected using the IR remote 120, at 1218. Thefile can then be provided to the DPVSM 102 for playback, as discussedabove.

[0106] It is noted that, while discussed above with reference toconverting files from the CD in the personal computer 110's CD player,the CD tracks could also be converted using the DPVSM 102 with theinitial playing occurring in the audio system 118, i.e., on a remote ormedia network disk player, coupled via the DPVSM 102 to the local areanetwork. Such a system is generally similar to the system describedabove with reference to the video streams and thus is not duplicatedhere.

[0107] Wireless 802.11 Remote

[0108] The digital personal media stream manager (DPVSM) embodimentsdiscussed above—both audio and video—are controllable via an infrared(IR) remote control. While inexpensive, such remote controls, however,depend on line-of-sight for functioning and thus are generally limitedto a single room use. Accordingly, one aspect of the present inventionis to provide an enhanced remote control for use in various rooms of ahouse or other space. In particular, as will be discussed in greaterdetail below, a wireless radio-signal remote control, such as a wirelesslocal area remote, such as a wireless 802.11 remote, is provided, forcontrol of DPVSM functionality. The wireless 802.11 remote controlbecomes an addressable device and can stay with the user throughout thehouse and used for control of network devices, such as the DPVSM 102 andattached devices. In addition, in certain embodiments, the handset canbe provided with voice capabilities and can be used as a voice over IPhandset (e.g., packet telephony or telephony over LAN functionality) orfor voice-portal control of the DPVSM 102. Advantageously, the system ofthe present invention allows an Internet telephone call to be receivedby the user even if not present at the computer when the call arrives,by use of the remote, instead of missing the call or forwarding it tovoice mail. Additionally, in certain embodiments, the remote 802.11could also function as a personal digital assistant (PDA), allowingaccess to the user's personal computer files. Such an embodiment thuscould run known PDA interfaces, software and/or operating systems.

[0109] Turning now to FIG. 13, a diagram of an exemplary systemaccording to an embodiment of the present invention is shown. The systemof FIG. 13 is generally similar to that of FIG. 1A and FIG. 1B. As such,only relevant components are shown. The system of FIG. 13 includes DPVSM102, personal computer 110, and 802.11 remote 1300. The 802.11 remote1300 includes an IP telephony controller 1302 and a DPVSM controller1304, as will be explained in greater detail below. Similarly, thepersonal computer 110 includes an 802.11 wireless interface 212 and aVoIP interface engine 1306. The VoIP interface engine 1306 may functionas an IP telephony gateway and may also itself support an IP telephonyclient. Thus, the VoIP interface 1306 may be embodied as an H.323 or SIPgateway.

[0110]FIG. 14A and FIG. 14B illustrate an exemplary wireless remoteaccording to an embodiment of the present invention. As shown, theremote 1300 includes a speaker 1312, a microphone 1314, and a display1308. The display may be implemented as an LCD display. In theembodiment illustrated, the display 1308 is a touchpad display and thusfunctions as a “virtual” keypad; in other embodiments, a separatephysical keypad and display may be provided. As shown in FIG. 14A, thedisplay 1308 may be used to select a mode 1309, i.e., telephone, video,or audio control. If the user chooses the telephone mode, then thedisplay shows a virtual telephone keypad 1310, which can be used to makeand receive calls.

[0111] In the alternative, the user can select the audio or video modes.If the user selects audio or video mode, then a display generallysimilar to that discussed above for the personal computer control of theaudio and video streams would be displayed. The 802.11 remote 1300 thanfunctions as a network client in a manner similar to the personalcomputer 110. If, for example, audio mode is selected, then as shown inFIG. 14B, an the display 1308 shows a jukebox select screen 1316. Thejukebox select screen 1316 can be used in a manner similar to thatdiscussed above with reference to the audio stream manager. The wirelessremote could also be used to download program schedules, media files,and the like, in a manner similar to that discussed above.

[0112]FIG. 15 is a block diagram illustrating an exemplary 802.11 remotecontrol 1300 according to an embodiment of the present invention. Asshown, the remote 1300 includes a control processor 1500, an 802.11interface 1502, and a GUI display 1308 which may implement a telephonykeypad 1310. The remote 1300 also includes a speaker 1312 and microphone1314. The control processor 1500 implements a wireless LAN interface1301, the telephony interface 1302, and the DPVSM controller 1304. Aswill be discussed in greater detail below, the wireless LAN interface1301 provides access to the wireless LAN, and may implement the IEEE802.11 standard. The telephony interface 1302 implements an IP telephonestandard, such as H.323 or SIP. The DPVSM controller 1304 allows theremote 1300 to control the DPVSM 102 via the wireless LAN.

[0113] Operation of an embodiment of the 802.11 remote control is shownby way of the signaling diagram of FIG. 16. In particular, shown is useof the 802.11 remote control 1300 to make and receive a telephone call,at 1601 and 1603, respectively. Shown are a PSTN connection 1600, modem106, 802.11 router 108, personal computer 110, cable box 112, DPVSM 102,video recorder 114, TV 116, and 802.11 remote 1300.

[0114] To make a phone call, the user of the 802.11 remote 1300 selectsthe telephone mode (FIG. 14) and dials the phone for the called partynumber. A call setup request message including a called party number issent from the remote 1300 and, particularly, its telephony interface1302, to the personal computer 110 via the 802.11 router 108, at 1602,1604. As noted above, in certain embodiments, the IP telephone system isbased on the Recommendation H.323 or Session Initiation Protocol,although other IP telephony standards can be employed. At 1606, thepersonal computer 110 activates its IP telephony program 1306. Thepersonal computer 110 then undertakes its portion of call setup with theremote 1300 at 1605. When this is accomplished, the personal computer110 attempts to complete the call with the outside network at 1608. Inthe embodiment illustrated, the personal computer 110 communicates viathe router with the modem 106, at 1610, after making the necessaryprotocol conversions to use the outside network. Call setup is then donevia connection 1600 and the external telephony provider at 1612. As isknown, an external telephony provider can then either render the call onits end over the Public Switched Telephone Network or the Internet. Thepersonal computer 110 then supervises the voice connection between theremote 1300 and the external connection 1600.

[0115] Call reception is handled similarly and is shown at 1603. At1614, a call is received at the connection 1600, which is then routedvia the modem and the router to the personal computer 110. The personalcomputer 110 activates its IP telephony program 1306 at 1616 and sends acall setup message to the remote 1300 via the router 108, at 1618, 1620.At 1622, 1624, the remote 1300 responds with its call setup responsesequence. A media channel is then opened between the personal computer110 and the remote 1300, at 1626, 1628; the personal computer 110 itselfmaintains the connection to the PSTN 1600.

[0116] As discussed above, the 802.11 remote 1300 can also be used tocontrol the DPVSM 102 and, in particular, its video and audio handlingcapabilities, in a manner similar to that discussed above. Depending onthe embodiment, such control can be exercised either through thepersonal computer 110 using its 802.11 remote interface (FIG. 1) ordirectly to and from the remote 1300 itself.

[0117] Control via the personal computer 110 is shown at 1701, 1703. At1702, the user of the remote 1300 can select a program or audio file andtransmit the choice to the personal computer 110 via the router 108, at1704. The personal computer 110 then forwards commands or files to theDPVSM 102 via the router, at 1706, 1708. Broadband video and/or audio,as well as video and audio files would then be handled as discussedabove in the “System Overview” section. It is noted that, in certainembodiments, actual audio and video files can be transmitted to theremote 1300 for display or playback, although resolution and fidelitymight be less than on the television or personal computer system.

[0118] Because the remote 1300 also functions as a network client, incertain embodiments, the remote 1300 may be equipped with sufficientprocessing power and/or memory to directly control the DPVSM 102,without intervening support from the personal computer 110. Thus, asshown at 1705, the remote 1300 can communicate directly with the DPVSM102 using its DPVSM control 1304 via the router 108 at 1710, 1712.Again, in such an embodiment, media streams and/or files would behandled similarly to the manner discussed above. In certain embodiments,of course, it may be necessary for communication to occur through thepersonal computer 110, which may maintain the media file database(s), asdiscussed above.

[0119] Electronic Messaging Control

[0120] In addition to providing local remote capabilities using the802.11 remote or an IR remote, as discussed above, embodiments of thepresent invention also provide access to the DPVSM 102 from remoteoff-site locations. Discussion of such remote control is in the contextof remotely programming a video recording device, it being understoodthat the techniques discussed herein are applicable to other specificremote control functions.

[0121] According to one embodiment of the present invention, an e-mailcontrol capability is provided. In particular, in such an embodiment,the personal computer 110 and, specifically, the e-mail system may beprovided with a DPVSM e-mail control module. The DPVSM e-mail controlmodule is adapted to read a specially-formatted e-mail having a show,time and date identified. The DPVSM e-mail control module then sends oneor more control messages via the local area network to the DPVSM 102,for recording. Such control commands may be in any format readable bythe DPVSM.

[0122] A block diagram of an exemplary personal computer 110 employingthe DPVSM control module is shown in FIG. 18. In particular, FIG. 18shows personal computer 110 including an e-mail system or client 1802.The e-mail system 1802 may be embodied as any of a variety of knowne-mail systems, such as Microsoft Outlook or Netscape Communicator. ADPVSM e-mail control module 1800 may be provided, according toembodiments of the present invention. The DPVSM e-mail control modulemay be embodied as a plug in for the e-mail program 1802. In particular,in certain embodiments, the DPVSM control program 312 may be providedwith one or more APIs (application programming interfaces) to allowvarious control applications such as the DPVSM e-mail control program1800. The DPVSM e-mail control program 1800 is adapted to read a specialcontrol e-mail and send one or more control commands to activate andcontrol the DPVSM 102 in response. The DPVSM 102 can then control therecording of one or more shows, in a manner similar to that discussedabove.

[0123]FIG. 19 is a diagram of an exemplary e-mail control message 1900for use in conjunction with the DPVSM e-mail control program 1800 ofFIG. 18. As shown, the e-mail control message 1900 includes a subjectline 1902. The subject line 1902 includes an entry “Digital DPVSM,” orother title that is read by the DPVSM e-mail control program 1800 toidentify the associated message as a DPVSM control message. In theembodiment illustrated, the associated text of the message 1904 includesDate, Time, Channel, Duration, and Password entries. In certainembodiments, if security is an issue, standard encryption can be appliedto encrypt the e-mail and protect the password. The Date, Time, Channeland Duration entries allow for unique selection of the program to berecorded. The Password entry allows the user to be uniquely identified,so that a third party cannot illicitly seize control of the DPVSM 102.Thus, in certain embodiments, the DPVSM e-mail control program 1800maintains a password file in memory of the user and password. As will bediscussed in greater detail below, the message is identified as a DPVSMcontrol message, and the DPVSM 102 is programmed in response thereto.

[0124] This is illustrated with reference to the flowchart of FIG. 20.In particular, at step 2002, a user can compose a DPVSM e-mail controlmessage 1900, either at the user's laptop computer or at a guestcomputer. At step 2004, the e-mail is received at the personal computer110, by the personal computer's e-mail client 1802. The DPVSM e-mailcontrol program 1800 reads the subject line and recognizes the messageas referring to a DPVSM control message. At step 2008, the controlparameters are converted to control parameters readable by the DPVSM102. Finally, at 2010, the control parameters are then sent to the DPVSM102, in step 2010. The DPVSM 102 then controls the video recorder 114.

[0125] Signaling for such an embodiment is shown with reference to FIG.21.

Alternatively, at 2115, the DPVSM 102 could transmit theprogramming information to the video recording device 114 and program itthen. When the media stream(s) arrive, the DPVSM 102 could then simplyact as a conduit for the media stream rather than an active programmingdevice.

[0126] Instant Messaging Control

[0127] According to another embodiment of the present invention, a usermay remotely control the DPVSM system 100 by using a special DPVSMInstant Messaging control message. The user's home personal computer hasan Instant Messaging client including a DPVSM IM Control module plug in,that recognizes the DPVSM Instant Messaging control message. The DPVSMcontrol module plug in then sends a message with the program informationto the DPVSM, which controls the programming of the video recorder.

[0128]FIG. 22 illustrates an exemplary personal computer 110 includingan Instant Messaging system or client 2202. The Instant Messaging system2202 may be implemented as a known instant messaging system, such asWindows Instant Messenger or AOL Instant Messenger. Also shown is aDPVSM IM control module plug in 2204 according to embodiments of thepresent invention. The DPVSM IM control module plug in 2204 functions toread an IM control heading defining a message as a DPVSM controlmessage; generate a confirmation; and translate the message into aDPVSM-readable control command, sent by the DPVSM controller 312 (FIG.12) to the DPVSM 102. The DPVSM 102 then programs the video recorder torecord the program at the designated time.

[0129]FIG. 23 illustrates an exemplary IM control message according tothis embodiment of the present invention. The message 2301 includes aheader indicia 2302 and a message body 2304. The header indicia as shownis DPRR, though any other predetermined indicia could be used. Themessage body 2304 includes date, time, channel, duration, and a userpassword. As noted above, the DPVSM IM control module 2204 reads themessage header 2302 and then knows to read the body of the message.

[0130] A flowchart illustrating operation of an embodiment of thepresent invention is shown in FIG. 24. At step 2402, the user cancompose the IM control message 2301 at a remote location. At step 2404,the IM control message 2301 is transported in a standard manner to thepersonal computer 110. At step 2406, the IM client 2202 decodes themessage and the DPVSM IM control module 2204 recognizes the message asreferring to DPVSM control. At step 2408, the DPVSM IM control module2204 converts the IM message into a control command format readable bythe DPVSM 102. At step 2410, in certain embodiments, the DPVSM IMcontrol module 2204 sends a confirmation message to the sender. This canidentify the channel and other parameters and provide an indication thatit has been received. Finally, at step 2412, the command is sent to theDPVSM 102 and stored until the time to execute the recording. Asignaling diagram showing operation of an embodiment of the presentinvention is shown in FIG. 25. Shown are a remote PC 2100, cableconnection 104, modem 106, 802.11 router 108, personal computer 110,cable box 112, DPVSM 102, video recorder 114, and television 116. At2502, the user at the remote PC 2100 composes a DPVSM IM controlmessage, such as that discussed above. The IM provider then sends themessage to the user's home personal computer 110, via the cableconnection 104, modem 106 and router 108. At 2504, the personal computer110's IM system and, particularly, the DPVSM IM control module 2204,sends a confirmation message back to the user at the remote PC 2100,once the DPVSM IM control message 2301 has been read. The DPVSM controlmodule 312 of the personal computer 110 then sends one or more commandsto the DPVSM 102 via the router 108, at 2506, with the appropriateprogramming instructions. These are then stored until the designatedtime; alternatively, the video recording device 114 can receive itsprogramming instructions when they arrive at the DPVSM 102. Thebroadband video is received at the DPVSM 102 and video recorder 114, at2508. At 2510, the video recorder 114 activates and at 2512, the videois recorded.

[0131] Short Message Service Control

[0132] According to another embodiment of the present invention, a ShortMessage Service (SMS) equipped telephone can be used to control theDPVSM 102. In particular, a SMS service provider may be adapted todetect a special SMS DPVSM control message and convert the SMS messageto a form readable by the DPVSM client on the local personal computer.For example, such a control message may be implemented as an e-mailcontrol message or even an IM control message, such as those discussedabove. The control message is received by the personal computer 110 andthen used by the DPVSM 102 to program the video recorder, in a mannersimilar to that discussed above.

[0133]FIG. 26 is a block diagram illustrating a system 2600 for enablingan SMS equipped telephone to program the DPVSM 102. In particular, thesystem 2600 shown in FIG. 26 includes a cellular telephone 2602 havingSMS capabilities, a cell provider 2604, and DPVSM system 100. The DPVSMsystem 100 may be generally similar to those discussed above withreference to FIG. 1A and FIG. 1B.

[0134] The cell provider 2604 serves as the SMS service provider andmaintains in conjunction with the SMS service, a DPVSM control detector2606, DPVSM command generator 2608, and DPVSM name database 2610. TheDPVSM control detector 2606 detects whether a received SMS message is aDPVSM control message, and accesses the DPVSM name database 2610 for thee-mail or IM address of the user. The DPVSM message converter 608 thenconverts the SMS DPVSM parameters in the message to a control messageformat readable by the personal computer 110, such as e-mail or IM. TheDPVSM message converter 608 then sends the corresponding e-mail or IMmessage to the user's personal computer which decodes it and uses it togenerate one or more control commands for control of the DPVSM 102, in amanner similar to that discussed above with reference to E-Mail and IMControl.

[0135] An exemplary SMS message for DPVSM control is shown in FIG. 27.The SMS message 2700 is generally similar to those discussed above withreference to the e-mail and IM embodiments. Thus, the SMS message 2700includes a DPVSM identifying header; date; time; duration; channel; andpassword parameters.

[0136] As noted above, the SMS DPVSM control message 2700 is received bythe DPVSM detector 2606 which then accesses the DPVSM names database2610. The DPVSM names database 2610 includes entries corresponding tousers' cell phone numbers and e-mail or IM user name, as shown in theexemplary database entry 2800 of FIG. 28.

[0137] The entries in the DPVSM names database 2610 could be set by asystem administrator or other administrative entity. According to aparticular embodiment, the DPVSM names database entries 2800 are set byusers via the World Wide Web or Internet access. For example, as shownin FIG. 29, the SMS/Cell provider maintains a web server 2900 inconjunction with the SMS server 2604. The web server 2900 maintains aweb page interface 2904 that allows the user to log in and make theDPVSM names database entries using standard form-making script 2902. Theentries can then be provided to the SMS server 2604. It is noted that,in certain embodiments, the SMS server and the web server may be thesame instrument. Thus, the figure is exemplary only.

[0138]FIG. 30 is a flowchart illustrating database entry according to anembodiment of the present invention. In step 3002, the user can log into the cell or SMS service provider's web site 2900. Log in can include,for example, the user registering and providing a personalidentification number, for example. The user can then enter the user'scell phone number, user ID, and e-mail or IM name, in step 3004.Finally, at step 3006, the entry is provided to the database 2610 at theSMS server 2604.

[0139]FIG. 31 is a flowchart illustrating operation of use of SMSmessaging to control the DPVSM 102 according to an embodiment of thepresent invention. At step 3102, the user can compose an SMS DPVSMcontrol message 2700 using his cell phone. As discussed above, such amessage 2700 typically includes a DPVSM identifier, a password, andtime, duration and channel information. At step 3104, the SMS DPVSMcontrol message 2700 is sent to the SMS server 2604. The SMS server 2604recognizes the message as relating to DPVSM control by its header, atstep 3106. The DPVSM detector 2606 then accesses the DPVSM database 2610for the caller's e-mail (or IM) address; the DPVSM detector can identifythe user's telephone number by standard calling number identificationtechniques. Once the e-mail address (or IM) is recognized, at step 3110,the DPVSM message converter 2608 converts the SMS control message to acontrol message. This message is sent to the messaging client at theuser's PC 110, at step 3112. Finally, in step 3114, the user's PC and,particularly, an e-mail DPVSM control unit or an IM DPVSM control unit,such as those described above, processes the message to generate one ormore control commands. The DPVSM 102 can then control the programming ofthe video recorder as discussed above.

[0140] Voice Portal Control

[0141] According to another embodiment of the present invention, a voiceportal control is provided to control the programming of the DPVSM. Moreparticularly, in such an embodiment, a user can simply respond to one ormore interactive voice response queries to program the DPVSM. Such avoice portal may be used by a party calling in on a standard telephone,or through use of the networked wireless 802.11 remote control discussedabove.

[0142] For example FIG. 32 illustrates an exemplary user interactionwith a voice portal for controlling a DPVSM 102 according to embodimentsof the present invention. At 3250, after the user calls in or otherwiselogs in, the voice portal responds “Welcome to your DPVSM.” Next, thevoice portal prompts to the user to “Enter your password,” at 3252. Oncethe user does so, and the password is confirmed, the user is requested,at 3254, to speak or enter a date, time, channel and duration ofrecording. Once the user makes the appropriate entries, as will bediscussed in greater detail below, the voice portal server contacts theDPVSM system 100 to cause the video recorder 114 to record thedesignated program. In particular, as will be discussed in greaterdetail below, once the voice entries have been made, the voice portalserver converts the entries into a DPVSM system readable message, suchas an email or an IM message, and then sends it to the user's PC. Theuser's PC 110 accepts the message and instructs the DPVSM 102accordingly. The voice portal may be implemented to respond to voicecommands through known voice recognition techniques, or to keypad input,such as via DTMF tone recognition.

[0143]FIG. 33A illustrates an exemplary voice portal DPVSM controlsystem 3300 a according to an embodiment of the present invention. Asshown, the system 3300 a of FIG. 33A includes a voice portal server 3202a having a voice portal 3304, a voice-to-email (or IM) converter 3306and a database 3308. The voice portal server 3202 a operably couples viae-mail or IM messaging to the DPVSM system 100.

[0144] According to a particular embodiment, the DPVSM names 3308database entries are set by users via the World Wide Web or Internetaccess. For example, as shown in FIG. 34, generally similar to the SMSserver of FIG. 29, the voice portal provider maintains a web server 3400in conjunction with the voice portal server 3202 a. The web server 3400maintains a web page interface 3404 that allows the user to log in andmake the DPVSM names database entries 3402. The entries could be madeusing standard form-making script, for example. The entries can then beprovided to the voice portal server 3202. Actual entries may be similarto those of FIG. 30.

[0145] In operation, as shown in FIG. 35, the user of telephone 3310,which may be a cell phone or a remote landline telephone, calls in atthe voice portal server 3202 a in step 3500. The voice portal server3202 a may be provided, for example, by a service provider and thenumber dialed may be a 900 or 800 (toll free) number. The calling partycan be identified by either a calling party identification technique, orby the spoken password, or a combination thereof. The voice portalcontrol 3304 provides the interactive voice response control describedabove with reference to FIG. 32, in step 3504. That is, the user inputsthe desired program recording information. The database 3308 provides acorresponding e-mail address or IM user name. In step 3506, theconverter 3306 converts the user inputs from the voice or IVR responseinputs into the associated e-mail or IM messaging control message, suchas the e-mail or IM control message discussed above. These messages areprovided to the user's home personal computer 110 and, particularly,read by the PC's DPVSM control system 312, in step 3508. Finally, thepersonal computer 110 sends control commands to the DPVSM 102 itself, instep 3510, which programs the video recorder 114 in response thereto.

[0146] In the voice portal embodiment discussed above, the voice portalengine is implemented by a service provider at a remote server. In otherembodiments, such a voice portal may be provided at the user's personalcomputer 110 itself. A block diagram of such an embodiment is shown inFIG. 32B. More particularly, FIG. 32B illustrates telephone 3310 and aportion of the DPVSM telecommunications system 100. Shown is a blockdiagram of a personal computer 110 including voice portal 3202 b. Thevoice portal 3202 b couples to the DPVSM control 312 and to a memory 304for storing voice portal information. In particular, the memory 304stores one or more files 3212 of voice parameters for the systemcommands of FIG. 32 and files that allow conversion between voice portalinputs and DPVSM recognizable commands. In certain embodiments, thevoice portal may be a submodule of the DPVSM control 312. The voiceportal 3202 b couples via a modem card 3220 to the PSTN (not shown). Thevoice portal 3202 b may be implemented using known voice recognitiontechnology.

[0147] Operation of this embodiment of the present invention is shownwith reference to the flowchart of FIG. 36. At step 3602, the user callsin from the telephone 3310 to his personal computer 110. As noted above,the call is to the user's home telephone number; the call is receivedvia modem 3220, which is coupled to the phone line. At step 3604, thevoice portal 3202 b generates the voice prompts to allow the user toinput the programming information, which is then received by the voiceportal 3202 b. In response, in step 3606, the voice portal 3202 baccesses the database 3212 to convert the received inputs into controlcommands readable by the DPVSM 102. Finally, at step 3608, the DPVSMcontrol 312 causes the commands to be transmitted to the DPVSM 102(FIG. 1) itself. The DPVSM 102 then controls the video recorder 114 forthe recording of the program.

[0148] It is noted that in the voice portal embodiments discussed above,the user can speak the actual program name and related information. Inother embodiments, however, the voice portal system could maintain adatabase of programs and show times, each having a unique numericalidentifier. The user could then log in to a web site to determine theparticular show's identifier, then dial in to the voice portal and inputthe identifier, either by speaking or by DTMF or other keyed input.

[0149] Context-Based Search System

[0150] The above-described embodiments for remote control of the DPVSM102 and program recording generally assume that the user has an idea ofwhat channel and time the show occurs. It may, however, be the case thatthe user has only a general idea of the time, date and channel a show ison. This may particularly be the case if the show is a one time sportingevent. A context-based search system according to embodiments of thepresent invention allows a user to control his DVPSM remotely, even whennot immediately possessed of complete programming information.

[0151] Operation of such an embodiment of the present invention is shownmore particularly with reference to FIG. 37. In a step 3702, a usercomposes a DPVSM control message, such as an e-mail, IM, or SMS message,or logs in to a voice portal, such as described above. At step 3704, thesearch system extracts keywords from the message or other inputs. Forexample, the search system could maintain a database of keywords such as“football,” “boxing,” or program titles and network, or approximatedates or ranges of dates. Next, at a step 3706, the search systemsearches a program database for occurrences of the keywords. If found,the search system composes a selection message, identifying programs inwhich the keywords are found, and sends it to the user. At a step 3710,the user can receive the message and make the selection. In oneembodiment, each choice may be provided with a one or two digitidentifier. When this is received back, the DPVSM recording may occur.

[0152] An exemplary DPVSM context-based search system according toembodiments of the preset invention is shown in FIG. 38. The system 3800includes DPVSM system 100, server 3802, remote user 3804, and one ormore network servers 3806 a-3806 n. The DPVSM system 100 may begenerally similar to that discussed above. The network servers 3806a-3806 n provide programming information to the server 3802 databases,as will be explained in greater detail below.

[0153] The search server 3802 includes a message receiver 3902, akeyword database 3808, a program database 3816, a channel access searchunit 3810, a keyword extractor 3812, a message search unit 3814, aconfirmation message generator 3818, and a DPVSM message generator 3820.The message receiver 3902 receives the user's control message; the user3804 may employ any of the above-described remote access methods toaccess the search system 3802.

[0154] As will be explained in greater detail below, the keyworddatabase 3808 maintains a listing of program keywords that can beextracted from the incoming user message. The keyword extractor 3812receives the incoming message, accesses the keyword database 3808 andextracts any keywords from the message. The message search unit 3814uses the extracted keyword(s) to search the program database 3816, whichis the listing of program times and scheduling. The program database3816 may be programmed via the channel access search unit 3810, whichaccesses the network servers 3806 for programming information. Theconfirmation message generator 3818 generates a confirmation orselection message which is sent to the user once the program databasehas been searched. The DPVSM controller 312 then receives the user'sselection and sends control messages to the DPVSM system 100. The DPVSMsystem can then convert the control message to one or more controlcommands for causing the DPVSM 102 to program the video recordingdevice.

[0155] Operation of an embodiment of the present invention isillustrated more particularly with reference to the signaling diagram ofFIG. 39. Shown is the search system 3802, a remote user 3804, and theDPVSM system 100.

[0156] At 3904, the user's programming control message is sent to thesearch system 3802. In particular, a message receiver 3902 receives theincoming message from the user. The message may be in a Short MessageService format, an Instant Messaging format, an e-mail format, or avoice portal format. The message receiver sends the message to thekeyword extractor 3812, at 3906. The keyword extractor 3812 accesses thekeyword database 3808, at 3908. The extracted keywords are provided tothe message search unit 3814, at 3910. At 3912, the message search unit3814 accesses the program database 3816. The results, if any, are thenprovided to the confirmation message generator 3818, at 3914. Theconfirmation message generator 3818 then, at 3916, generates a messageincluding search matches in the appropriate received format. Thus, forexample, if the message was an IM message, the confirmation message willlikewise be an IM message. The user can then make a selection of theappropriate program and return an acknowledge message, at 3918. TheDPVSM controller 3820 then receives the program information at 3920.Finally, the DPVSM controller 3820 sends one or more control messages,such as the e-mail or IM control messages discussed above, to the DPVSMsystem 100, at 3922. Typically, the message is received by the user's PC110, which generates one or more control commands, and handling proceedsin a manner similar to that discussed above.

[0157] As noted above, the search system 3802 can access one or morenetwork servers 3806 to determine programming schedules. This isillustrated in FIG. 40. Shown are the channel access search unit 3810and the program database 3816, as well as an exemplary network server3806. The channel access search unit may be an automated Internetbrowser plug in that periodically accesses the network server 3806, at4002. The information is received at 4004 and provided to the channeldatabase 3816 at 4006. Any formatting changes, if necessary, can be madeby the channel access search unit 3816.
